3 cesium iodide ( CsI ) / bismuth oxysulfide ( Gd2O2S ) + lens / optical fiber + CCD / CMOS : X-ray first through the scintillator or phosphor visible light conversion screen, X-ray photons into visible light image, and then passed The lens or optical fiber sends the visible light image to the optical system, which is acquired by the CCD and converted into an image electrical signal.
4 CsI (Gd2O2S) + CMOS: This type of technology is limited by the poor spatial resolution of indirect energy conversion. Although a large number of low-resolution CMOS probes are used to form a large-area matrix, it is not able to effectively compete with the TFT panel.
